| In order to have VESA_800x600 use the full screen of the virtual console,
| run the following:
| 
| # vidcontrol -g 100x37 VESA_800x600 -f whatever_font_you_want
| 
| This will resize it to the said geometry of 100x37 chars at a resolution 
| of 800x600.
| 
| The rc.conf entries look like this on my box:
| 
| allscreens_flags="-g 100x37 VESA_800x600"
| font8x16="/usr/share/syscons/fonts/iso15-8x16.fnt"
| 
| This should work just fine and fill up the whole available screen.
| 
| I just don't like the low refresh rate of 60Hz, after some time, it blinds
| my head :)
| 
| Does anyone know how to increase the vert. refresh at 800x600?

  Hi,
  
  Thanks for the rc.conf tip.
  
  60Hz is the max value that my 14' monitor handle so it is good that default 
  refresh is 60Hz.
  
  Thanks,
